174 Parameters
22.03 Dec time1 Defines deceleration time 1 as the time required for the speed
to change from the speed value defined by parameter 19.01
Speed scaling to zero.
If the speed reference decreases slower than the set
deceleration rate, the motor speed will follow the reference
signal.
If the reference changes faster than the set deceleration rate,
the motor speed will follow the deceleration rate.
If the deceleration time is set too short, the drive will
automatically prolong the deceleration in order not to exceed
drive torque limits. If there is any doubt about the deceleration
time being too short, ensure that the DC overvoltage control
is on (parameter 47.01 Overvolt ctrl).
Note: If a short deceleration time is needed for a high inertia
application, the drive should be equipped with an electric
braking option e.g. with a brake chopper (built-in) and a brake
resistor.
